Title: Improvements in and relating to moulded, waterproof fibrous products and process forthe manufacture of same
IPC: D21H23/10
Filed: 1930-07-21
Abstract: In preparing waterproofed fibrous products from a mixture of aqueous fibrous pulp and an aqueous dispersion of waterproofing material such as asphalt, the latter is precipitated upon the individual fibres by forming a fixing agent in the mixture at a pH value corresponding approximately to the iso-electric point of the said agent.  The invention is particularly applicable to the process described in Specification 359,950 in which the pulp stock is deposited by pressure or suction in foraminous moulds.  In practice, reagents are added to the mixture of stock and dispersed asphalt which will form a precipitating agent for the asphalt, for instance sodium resinate and alum, which react to form aluminium resinate, or sodium silicate and alum, which react to form aluminium hydroxide.  The pH value corresponding to the iso-electric point of the fixing agent is first determined, and a suitable quantity of one of the reagents, e.g. sodium silicate, is added to the mixture of pulp stock and asphalt dispersion.  The other reagent, e.g. alum, is then added in quantities sufficient to bring the pH value of the mixture to the previously determined pH value corresponding to the iso-electric point of the fixing agent.  The amount of the second reagent to be added to effect this is determined by means of a preliminary test. When the iso-electric point is reached, the flocculent precipitate of aluminium hydroxide causes practically all the asphalt to be fixed on the fibres of the stock, leaving the aqueous vehicle free of asphalt and permitting its free removal.  The dispersion of waterproofing material is preferably an aqueous dispersion containing a nonfluent bitumen such as asphalt of 100-200 DEG  F. melting point made by the processes described in Specifications 244,135, 315,839, [both in Class 96, Paper &c.], or 343,427, [Group III].  An aqueous dispersion of rubber may also be used.

Title: Improvements in or relating to insulated electric conductors
IPC: H01B7/28
Filed: 1934-06-16
Abstract: 439,831. Insulated conductors. ASSOCIATED ELECTRIC LABORATORIES, Inc., 1033, West Van Buren Street, Chicago, U.S.A. June 16, 1934, No. 17901. Convention date, July 5, 1933. [Class 36] An insulated conductor, particularly for use on telephone switchboards, is made by first coating a wire with a layer of artificial silk or similar fibres which are capable of being rendered plastic by a solvent, such as acetone, and then applying one or more layers of fibrous material which is not affected by the solvent, the whole being subsequently saturated with the solvent for the first layer, thereby causing the outer surface of that layer to become plastic and to exude between the fibres of the outer layer so as to bind them together and to the first layer. In the construction shown, a conductor 5 having an enamel coating 6 is lapped with cellulose acetate threads 7 and is enclosed in a wrapping 8 of cotton threads, the insulated conductor thus formed being passed through acetone to cause the cellulose acetate threads to coalesce and bind the cotton threads together. In a modified construction the cotton threads are braided about the layer of cellulose acetate threads. The conductor may be flame-proofed by impregnation with chlorinated naphthalene. Specification 382,662 is referred to.

Title: Improvements in or relating to electrical measuring apparatus
IPC: G01R19/22
Filed: 1940-12-20
Abstract: 545,999. Thermionic valves. STANDARD TELEPHONES & CABLES, Ltd., BARNARD, R. M., and KRAM, W. Dec. 20, 1940, No. 17946. [Class 39 (i)] [Also in Group XXXVI] In apparatus for measuring electric currents at high frequencies, the current to be measured is connected to terminals B connected to the ends of the filamentary cathode H of a cylindrical diode, a meter M in the form of a galvanometer micro ammeter being connected between the anode A and one end of the cathode H. The sensitivity of the device may be increased by applying a relatively small polarizing voltage, e.g. from a battery, between the anode A and the cathode. In another form, Fig. 3, the polarizing voltage is produced by a battery F whilst a battery F1 and rheostat R2 shunting the meter produces a current in the meter which opposes the electron current so that the deflection is zero when no signal is present at the input. A polarizing current is passed through the heater by a battery F2 and rheostat R1, the voltage to be measured being impressed on the cathode circuit via a condenser C. In a second form, Fig. 4, for measurement in a H.F. circuit the diode is constructed to simulate a short length of a coaxial transmission line, the polarizing current being passed through the heater from a battery F2 having a voltage sufficiently high to allow the resistance r to be larger than the characteristic impedance of the circuit, condensers C confining the polarizing current to the circuit. A battery F1 and resistance R2 are provided to balance the standing anode current. The relations between the inductance L and the capacitance C are given by the equation Zk being the characteristic impedance of the network, the polarizing current being adjusted to produce a space charge such that R the resistance of the heater per cm. length and G the conductance per cm. length. For the balanced case in the measurement of the H.F. circuit, the diode is provided with two cathodes H, H1, Fig. 5, constructed as parallel filaments connected to input and output circuits I, O through transformers T1, T2. The polarizing battery F2 is connected between the mid points of windings of the transformer, and the batteries F1, F, resistance R2 and meter M function as shown in Fig. 4. Specification 168,394, [Class 39 (i)], is referred to.

Title: Improvements in and relating to the preparation of tetraalkylated tin
IPC: C07F7/22
Filed: 1965-04-30
Abstract: Tetramethyl tin is recovered from a solution consisting of tetramethyl tin and a watersoluble ether by contacting the solution with water thereby to form a tetramethyl tin phase and a water phase containing a water soluble ether; these phases are then separated. The ether has a high solubility in water at the extraction temp., i.e. 15-50 DEG  C., and is preferably infinitely miscible with water. The soluble can contain at least one methyl tin halide, this halide entering the water phase during contact of the solution with water. The initial solution can be formed by reacting methyl magnesium halide and tin tetrachloride, this solution is hydrolysed and the organic phase is extracted with water, e.g. at 15-50 DEG  C. and the tetramethyl tin phase is separated. The tetramethyl tin can be separated from the ether/water phase using a countercurrent extraction technique. Methyl tin oxides can be recovered from the water phase after removal of the ether by treatment with alkali.

Filed: 1944-09-28
Abstract: 608,219. Winding yarn. CLARK, D. M. (Abbott Machine Co.). Sept. 28, 1944, No. 18633. [Classes 120(ii) and 120(iii)] A yarn winding machine comprises a plurality of winding units, means for conveying said units in a procession around the machine, yieldable connecting means permitting momentary continued movement of at least a portion of the conveying means when movement of a winding unit is abnormally resisted by a non - travelling part of the machine and means actuatable in response to yielding of the connecting means to stop the conveying means. Each winding unit, comprising a motor-driven inner centre 60, retractable camoperated outer centre 100 and a suitable reciprocating thread-guide assembly, is connected to the endless conveying chain 14<SP>1</SP> by an extensible connection comprising pivoted links 15, 16, spring-urged at 19, and carrying a pin 20. When, by reason of part of a winding unit becoming stuck or a bobbin misplaced or absent, the winding unit offers undue resistance to movement, the link 15, 16 extends to bring the pin 20 in contact with a blade 25, pivoted at 27, to turn the same and throw out a mercury switch 30 to stop the main driving motor and also the unit motors 63. The main motor drives a drum the brake of which is held off by a solenoid, but upon the breaking of the switch 30, the brake is applied to stop the motor immediately. The new bobbin feed device comprises rails 400 down which. the bobbins slide to a gate device 401. 402, 408 oscillated by a shaft 403 through a rod 405 lifted by a pin 407 on a passing winding unit. The new bobbins are fed singly to further guides 409 beneath which they are received between spring-urged fingers 413 to lie horizontally therebetween and taken therefrom by the passing winding units. If a new bobbin is not in a position ready for release at position A. a feeler 422 on the shaft 403 will permit the rod 405 to fall to a position where a lug 420 will prevent the pin 407 on the winding unit from passing thus extending the links 15, 16 and stopping the machine. A similar operation ensues if a bobbin becomes misplaced between the gates 401, 408, a detector 501 bringing about the stopping of the machine. In a modification instead of the extendable link 15, 16 initiating the stop motion, the two contacts of a spring- urged switch are separately attached to two relatively movable portions of the machine, spring-biassed together. Upon movement of the feeler 422 or detector 501, above described, the winding unit at the bobbin-feeding station will displace the movable portion of the machine to stop the main and unit motors. Specifications 522,664, 608,219 and 608,302 are referred to.
